DRIVING AND REVERSING GEARING.

Application led February 3, 1913.

To all whom t may concern Be it known that I, HARVEY ELLIOTT, citizen ofthe United States, residing at Detroit, county of lNayne, State ofMichigan, have invented a certain new and useful Improvement in Drivingand Reversing Gearing, and declare the following to be a full, clear,and exact description of the same, such as will enable others skilled inthe art to which it pertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of thisspecilication.

My invention relates to a gearless driving and reversing clutch whichmay be used to advantage in connection with motor boats, hoistingapparatus, or other like installations, as shown in the accompanyingdrawings and more particularly set forth in the following specificationand claims.

The object of my invention is to produce an efficient and inexpensivedriving and reversing clutch, dispensing entirely with the trains ofgears usually employed in devices of this character-the constructionbeing such that the driving shaft while rotating in one direction may becoupled with a propeller shaft (for example) in line therewith, to drivea boat forward or to reverse the same as required.

Other advantages and improvements will be hereinafter set forth and moreparticu larly pointed out in the claims.

Referring now to the letters of reference placed upon the drawings Aindicates a driving shaft journaled at its lforward end in a suitablebearing in the inclosing case B, which is divided into two partslongitudinally, and ybolted together in line with the driving shaft. Therear end of the shaft A is preferably reduced in diameter and housed ina bushing o inserted in the propeller shaft C, as indicated in Fig. l ofthe drawings.

C denotes a collar keyed to the propeller shaft in turn bolted to asimilar collar carried by the shaft of the propeller blades (not shown).

C2 is a disk preferably integral with the propeller shaft to which isbolted an annular cone C3.

c is a thrust bearing between the shoulder a of the driving shaft andthe disk C2, and c2 is a similar thrust bearing between the collar C andthe projecting hub Z) of the bearing formed in the inclosing case B toreceive the propeller shaft C.

D indicates an annular shaft sleeved on the shaft A provided with a slotat d for the passage of a key A carried by the shaft A, the slot beingof sufficient length to admit of a longitudinal movement of the annularshaft along the shaft A, with which it is caused to rotate by the key A.

E denotes a cone-shaped ring housed within the cone C3 and keyed asindicated at e to the annular shaft D.

E is a movable key supported in the wall of the ring E adapted to bethrust outward into a key-way e', provided in the cone C3, through theaction of the spring E2.

F is a cone, of relatively dierent taper to the annular cone C3, sleevedon the annular shaft D, and provided with a key-way f to receive theprojecting key A carried by the driving shaft, whereby the cone F iscaused to rotate therewith while being adapted for longitudinal movementwith respect to the shaft.

F is a projecting sleeve preferably integral with the cone F, formedwith a flange F2 channeled to receive the friction rolls G carried bythe shifting fork G. At F3 the end of the sleeve F is given asubstantially cone-shaped formation with an annular recess f adapted toreceive the fingers 7L of the dogs H. The dogs H are pivoted to thecollar l which in turn is carried by lthe annular shaft D.

f2 is a port in the cone F through which oil may be delivered to theperiphery of the annular shaft D upon which the cone F is designed toslide.

G2 indicates a transverse shaft journaled in the frame A to which theshifting fork is keyed.

L indicates a supporting ring provided with ears Z pierced for thepassage of bolts Z by which the ring is secured to the projecting lugs bof the inclosing case B.

-M denotes an adjustable annular frame or cage sleeve over the cone Fand provided with a projecting hub M extending into the ring L.

L is a set-screw carried by the ring L to secure the hub to the ring,upon releasing which the frame may be adjusted to take up wear.

N denotes a vlurality of rolls mounted on the shafts in turn keyed orpinned to the annular frame M,-the shafts being Vfree to move along thepins to provide for tacting surface throughout their length with boththe inner face of the cone C3 and the outer face of the cone F, therebyinsuring an equal or like speed transmission between the graduallyincreasing diameter of the cone and the rolls throughout their entirelength. ny is a bushing on which the rolls rotate.

O is a casting bolted to the cone F and provided withan inclined slottedway O through which projects the spring E2 engaging the movable key E.

Having indicated the several parts by reference letters, theconstruction and operation of my device will be readily understood. Y

For purposes of description and to more clearly indicate the operationof the device, it is assumed to be employed in connection with a motorboat (not shown), though it is equally well adapted for otherinstallations.

When it is the desire of the operator to drive the mot-or boat forward,the lever G3v Y is manually placed in the position indicated in solidlines in Fig. 1 of the drawings. TvVhen in this position, the fingers h'of the dogs H, rest in the depressiony f formed in the periphery of thecone-shaped portion F3 of the projecting sleeve F, the fingers L bearingupon the inclined flange of the coli lar J, thereby securing the sleeveagainst accidental longitudinal movement with respect to the drivingshaft A. The movable key E carried by the cone-shaped ring E is forcedoutward and into locking relation with the annular cone C2 through theac tion ofthe spring E2, placed under increasing tension through therearward (or right hand). movement of the casting O bolted to the cone Fwhen the lever G3 is moved to the position indicated z-it being obviousthat the tension of the spring is increased due to its slid-ing up theinclined way formed in the casting. The cone-shaped ring E when broughtinto impinging relation with the innery face of the annular cone C3 willrotate the latter, causing the propeller blades to move with the driveshaft or in a forward direction.` Should the load, however, besufficient to cause slipping between the ring E and the inner face ofthe cone C3, the movable key E will lock the cone ring E in a positivedriving relation with the annular cone C3 immediately yupon the key Eregistering with the key-way e in the cone,- the spring E2 forcing thekey to its seat.

It will now be assumed that it is the desire of the operator to throwthe device into a neutrall position; z'. e., the engine being permittedto run without operating the propeller blades. To accomplish thisresult, the operating lever ,G3V is given a slight movement to the leftwhich serves to unseat the lingers h of the dogs VH from the depressionf in the cone-shaped portion F3, which action permits the spring K toforce the sleeve to the right along the driving shaft A, carrying withit the coneshaped ring E and at the same time automatically releasingthe movable key E from engagement with the annular cone C2,-it beingobviousthat the spring E2 engaging the movable key, being acted upon bythe inclined way in the casting O, will serve to withdraw the movablekey from its locking engagement with the annular cone when the sleeve Fis forced to the left due to the manual operation of the lever G3.

It will no-w be assumed that it is desired to reverse the directionpreviously taken by the propeller blades. This result is accomplished bya still further movement of the operating lever G3 to the left. Thisaction causes the cone F to move to the left sufficiently to forceoutward the rolls N into impinging contact with the inner face of theannular cone G3. The rolls contacting as they do throughout theil`length with the cone F, are rotated thereby in an opposite direction tothat taken by the cone F, and the driving shaft A,-at the same timedriving the annular cone C3-by a rolling contact with its inner faceinthe same direction as that taken by the rolls and in an oppositedirection to that taken by the driving shaft, thus reversing themovement of the propeller shaft C. 1t will therefore be obvious thatwhile the driving shaft 0perates in one direction only, the propellershaft may be actuated in either direction or remain at rest, as governedby the adjustment of the manually operated lever G3.

Attention is directed to the fact that when the lever G3 is again movedto the right,- to the position occupied when driving the boatforward,the cone-shaped portion F3 of the sleeve F will cause the dogs Hto tilt due to the action of the lingers 7b bearing thereon while thefingers L, bearing upon the inclined'face of the collar J will cause theannular shaft D to move slightly to the left and against the action ofthe spring K, thereby bringing the cone-shaped ring E, carried by theannular shaft, into impinging relation with the annular cone C3. Uponshifting the lever G3 to the left to either a neutral or reverseposition, the spring K will again become active forcing the annularshaft D to the right, thereby assisting in releasing the cone-shapedring E from engagement with the annular cone C3.
